Just wondering what the differences is in wagons between and EF S1 vs the EF S2/EL rear suspension. I just bought an EL wagon with rear swaybar, part code is BFR-47. I looked it up on the Whiteline website and they list a different one, I think BFR-38, for the EF S1. Just wondering what the difference between them is, and whether I can transfer it accross to my XR?

Hmmm thats what I thought too. I spoke to a friend at Pedders and he has no record of differences between suspension. His only thought was perhaps exhaust change or something similar, which affects swaybar shape, but not suspension pickup points. I will ring whiteline a little later this week, but it may be a case of getting under the car with the swaybar and having a look

Yep I realise that they didn't (still not really sure why they never put them in, espec in the XR wagons )

The things is, the retrofit kits from Whiteline list a different part number for EF S1, and EF S2/EL. Which is quite strange. I just bought an EL wagon with a (Whiteline) swaybar, and am trying to work out whether I can swap it over to my EF, or if it won't fit. In the pictures on whitelines website, its even a different shape!

As far as why they don't have rear sway bars - I remember many years ago (when I had a modified 5.0 VC Commondung) reading a magazine article on a heavily modified VC Commondung club racing car - and as part of it's suspension setup the rear swaybar was removed deliberately to achieve proper balance - ie. lower / stiffer shocks and springs + swaybar apparently made it prone to oversteer.

The leafs on the EA-ED are a different shape (at the leaf ends), wouldn't effect the setup.Essential diiferences are the round front eyes on commercials, and elliptical on wagons. XH utes have different front eye sizes too - outback, one tonne, etc.Whiteline list different nos on the front bars too - no difference there either - IIRC the EL bars are a bit cheaper. The 30mm front with a 20mm rear is a good ballanced setup.

Any one know what differences (if any) there is with the front sway bar between series 1 and 2 ef-el and the xr wagons?

If some one knows the sizes that'd be helpfull as I have measured my fairmonts and my xr wagons both ef and they seem to be 26mm is this correct? In the process of rebuilding front end and replacing all bushes so want to make sure before I buy the wrong size.

The difference between a S1 EF and S2 EF and EL is the U bolt size. It is much larger in the later group. The bar will be the same, hell, I have an EF bar on my EB diff, and they are different, so it is all possible.

In addition to the larger U bolt diameter, the bottom plate the bolts pass through also is larger to allow for the bigger hole size.

This is worthwhile upgrading your EF to anyway as it will be stronger.

Thats what my research has shown for the front. The EL's had a larger U-bracket. With the EF swaybars, the larger brakets are included, hence why the EF kits are a bit more expensive and have a different code. The EL wagon I bought has the 30mm front swaybar, still trying to decide whether to put it on the EF or EL haha.

The rear is the bit which gets me. No wagons had rear swaybars, XR's included, and from what I have read (mainly from Snap and BenJ) it makes a big difference. So I am definitely keen to put one in, just trying to work out if the one from the EL wagon I got will fit. I think it may have to be a trial fit to know for sure

Spot the Difference!

EF SI Swaybar (MOTORSPORT!)

EF SII/EL Swaybar

The Whiteline website shows two different bars, with a different end bend shape (unless is just the photo). I just noticed the EF swaybar, representing better value for money, can you see why
